The inner extrusion blocks of the first extrusion frame 33 and the second extrusion frame 34 are extruded and matched with the left end of the extrusion piece 3.

[0040] refer to Fig.11 and Fig.12 As shown, a screening device on a cylindrical cooler is shown, the inner side of the first guide frame 111 at the front end is fixedly connected with an electric push rod 4, the output end of the electric push rod 4 is fixedly connected with a second telescopic member 43, the electric push rod 4 is used to drive the second telescopic member 43 to move upward, the bottoms of the four corners of the second telescopic member 43 are fixedly connected with the first telescopic member 41, the second telescopic member 43 is used to drive the output end of the first telescopic member 41 to extend upward, the lower surface of the first telescopic member 41 is fixedly connected to the four corners of the upper surface of the telescopic storage box 112, the inner sides of the first telescopic member 41 are fixedly connected with elastic cloth 42, the first telescopic member 41 is used to drive the elastic cloth 42 to move upward at the same time, the lower surface of the elastic cloth 42 is fixedly connected to the upper surface of the telescopic storage box 112, when the elastic cloth 42 is driven to rise by the electric push rod 4, the electric push rod 4 can cover the area where impurities fall off to prevent impurities from falling everywhere, which helps to keep the working area clean and tidy, and can also reduce subsequent manual cleaning work.

[0041] The complete working principle and steps of the above embodiment are as follows:

[0042] refer to Figures 1 to 5As shown, when the screening device is in the urged state, the closing member 17 is sealed against the left side of the cooler body 14, the right side of the bottom of the force storage spring 19 is against the left side of the closing member 17, the force storage spring 19 is in a naturally relaxed state, the telescopic storage box 112 is in a contracted state, and the electromagnet 114 is in a powered-off state;

[0043] When the staff uses the screening device to screen the material output from the smelting kiln, first put the material in from the top of the feed port 15, and the material will be transported from the feed port 15 to the inside of the cooler body 14. At this time, the driving ring gear 13 is started, and the driving ring gear 13 can drive the cooler body 14 to rotate at the same time. At this time, the material can be turned over and cooled inside the cooler body 14. Since the internal rotation of the closure 17 is connected to the left end of the rotating frame 113, and the surface of the rotating frame 113 is symmetrically rotated and connected to eight electromagnets 114, the electromagnets 114 are energized to generate magnetism. When the material is turned over inside the cooler body 14, the metal impurities inside the material will be The electromagnet 114 adsorbs the material, thereby removing unnecessary metal impurities in the material, improving the purity of the material, and preventing the metal impurities in the material from causing wear to the production equipment of the next process. When the material is cooled, the retaining member 110 is pushed upward in the square hole of the connecting frame 18 to cause the bottom of the right side of the retaining member 110 to separate from the left side of the closing member 17. When the retaining member 110 moves upward, the force storage spring 19 is moved to a stretched state. At this time, the second fixing frame 16 needs to be pushed to the left. When the second fixing frame 16 moves to the left, it will drive the closing member 17 to move at the same time. At this time, the closing member 17 will separate from the fit with the left end of the cooler body 14, thereby The material inside the cooler body 14 can be taken out, and when the closing member 17 moves to the left, the electromagnet 114 is driven to move outward at the same time through the rotating frame 113, and the metal impurities in the material are adsorbed on the outer surface of the electromagnet 114, and when the second fixed frame 16 moves to the left, it drives the first guide frame 111 to move at the same time. Since the inner side of the first guide frame 111 is fixedly connected to the two ends of the left side of the telescopic storage box 112, as the first guide frame 111 moves to the left, the telescopic end of the telescopic storage box 112 is driven to move at the same time, and the right side of the telescopic storage box 112 is fixed to the upper surface of the first fixed frame 1 through the fixing column 115. At this time, the left side of the telescopic storage box 112 is moved to the left. When moving to the left, the telescopic storage box 112 will be pulled up laterally. When the telescopic storage box 112 is pulled up laterally, the support rod 116 on the outer surface of the telescopic storage box 112 will move to the left along the upper surface of the first guide frame 111 at the same time, so that the telescopic storage box 112 can move to the left more smoothly. At this time, the length of the telescopic storage box 112 after unfolding is greater than the length of the rotating frame 113, so that the metal impurities on the electromagnet 114 can completely fall into the telescopic storage box 112, and the electromagnet 114 is disconnected and the metal impurities will fall off the electromagnet 114 after the electromagnet 114 loses its magnetism, so that the metal impurities can completely fall into the telescopic storage box 112, thereby avoiding the scattering and loss of impurities.

[0044] refer to Figure 6 and Figure 7 As shown, when the screening device is in the promoted state, the rack 22 has not yet meshed with the gear 21;

[0045] As the cooler body 14 rotates, the cooler body 14 will drive the rack 22 to rotate at the same time. When the rack 22 rotates, the inner side of the rack 22 will mesh with the outer surface of the gear 21 and cause the gear 21 to rotate. The right side of the gear 21 is connected to the inner side of the bottom of the belt 2. As the gear 21 rotates, the rotating frame 113 will be driven to rotate at the same time through the belt 2. When the rotating frame 113 rotates, the electromagnet 114 will be driven to rotate at the same time, so that the electromagnets 114 on the bottom and top surfaces are switched, avoiding poor suction caused by excessive adsorption of the electromagnet 114 at a single position. After switching, the overall adsorption efficiency can be improved to ensure that the metal impurities in the material are fully removed.

[0046] refer to Figures 8 to 10 As shown, when the screening device is in the urged state, the rotating member 32 on the upper surface is engaged with the right side of the toggle member 31, the rotating member 32 on the lower surface is engaged with the left side of the toggle member 31, and the left side of the extruding member 3 is pressed and matched with the inclined surface of the extruding block inside the first extruding frame 33;

[0047] As the rotating frame 113 rotates clockwise, the extrusion pieces 3 on both sides will be driven to rotate simultaneously, and the left side of the bottom extrusion piece 3 will be out of contact with the inclined surface of the inner extrusion block of the first extrusion frame 33, while the left side of the top extrusion piece 3 will be in contact with the inclined surface of the inner extrusion block of the first extrusion frame 33 and slide to the left. As the top extrusion piece 3 moves to the left on the outer surface of the rotating frame 113, the top toggle piece 31 will be driven to move to the left at the same time. Since the top toggle piece 31 is engaged with the top rotating piece 32, the top toggle piece 31 will drive the rotating piece 32 to rotate when it moves to the left, and the rotating piece 32 can drive the top electromagnet 114 to rotate simultaneously when it rotates. As the rotating frame 113 drives the extrusion piece 3 to continue to rotate, the left side of the bottom extrusion piece 3 will be in contact with the inclined surface of the inner extrusion block of the second extrusion frame 34 and slide to the right. When the toggle member 31 slides to the right, the toggle member 31 at the bottom will slide at the same time. When the toggle member 31 slides to the right, the rotating member 32 at the bottom will rotate at the same time. When the rotating member 32 at the bottom rotates, the electromagnet 114 at the top will rotate at the same time. Since the toggle member 31 is meshed with the rotating member 32 through a cylindrical rod, when there is material between the toggle member 31 and the rotating member 32, it will not affect the rotation of the rotating member 32 driven by the toggle member 31. As the electromagnet 114 at the top and the electromagnet 114 at the bottom rotate intermittently, the electromagnet 114 can more comprehensively contact the metal impurities in the material, so that the impurities in the material are effectively adsorbed and reduced. In addition, during the rotation process, the electromagnet 114 can continuously change the contact position with the material, which is helpful to separate the magazine more comprehensively and avoid the accumulation of impurities on one side of the electromagnet 114.

[0048] refer to Fig.11 and Fig.12As shown, as the first guide frame 111 drives the telescopic storage box 112 to move to the left, the tops of the front and rear ends of the left side of the telescopic storage box 112 will drive the first telescopic member 41 to move simultaneously. At this time, when the first telescopic member 41 moves to the left, it will stretch the second telescopic member 43 to the left, and when the telescopic storage box 112 moves to the left, it will also drive the elastic cloth 42 on the front and rear sides to stretch to the left at the same time. At this time, the electric push rod 4 is started, prompting the electric push rod 4 to drive the second telescopic member 43 to move upward. When the second telescopic member 43 moves upward, it will drive the moving end of the first telescopic member 41 to move simultaneously, and when the moving end of the first telescopic member 41 moves upward, it will drive the elastic cloth 42 to move upward simultaneously. When the first telescopic member 41 moves upward, it can cover the upper surface of the telescopic storage box 112 to prevent impurities from falling everywhere, which helps to keep the working area clean and tidy, and can also reduce subsequent manual cleaning work.
